PHONOGRAPHY.

Specification of Letters Patent.

Patented Oct. 13, 1908.

Application filed. July 18', 1901., Serial No. 384,299.

To all whom it may concern:

Be it known that LISIDOR KITSEE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Im rovements in Phonography, of which'the ollowing is a specification. 4 My invention relates to an improvement in phonography. Its object is to produce an original record adapted to have therefrom, with the aid of photography, produced a number of copies.

In ap lication Serial No. 374,213, filed May 17t 1907, and in a plication Serial No. 380,960, filed June 26th 1907, I have described means, whereby with the aid of a liquid, colored so as to be opaque to the rays of light, or with the aid of a solid crayon, phonographic lines may be traced or drawn on a material transparent to the rays of light. I have found that in bothoases an original record, useful for the purpose of producing copies therefrom, can be made. I

will describe here both processes and the product resulting therefrom. I

In one case, that is, where the liquid is used, I preferably provide a reservoir containing the necessary liquid with means to cause the liquid to flow out of said reservoir in a stream fine enough, so as to produce a line of the necessary thickness, and I connect the vibrating diaphragm either directly or indirectly with the means whereby the liquid issues from the reservoir, in a manner so that the vibrations of the diaphragm will produce vibrations of said means, thereby producing the required undulatory line; but it is obvious that instead of a free-flowing liquid, a pen or ink stylus may be used. In the other case, that is, where a crayon or pencil isemployed, I connect to thestylus the pencil or crayon and trace on the transparent material the undulating lines in substantially the same manner as in the method aforesaid whereinthe'liquid is used, withthe excep-" tion that in this last case the crayon or penoil-has to be in contact with the material on which the lines are to be traced.

Different materials may be used for the purpose of having thereon reproduced the vibrations of the phonographic diaphragm, but I have found that glass in the first case and tracing cloth in the second case answers the ur ose well.

T e rawing represents in plan view part of ,a record made in accordance with my invention. v

In thisdrawing, 1 is the transparent material and 2 are the lines marked thereon with a material opaque to the rays of li ht.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. An original 'phonographic record consisting-of a transparent material and sound waves written thereon with a non-magnetic material opaque to the rays of light.

2. Any original sound record com rising a material transparent to the rays of ight and undulating lines of non-magnetic material representing sound Waves, said lines opaque to said rays of light.

3. An original phonographic record consisting of a plate or sheet of a material transparent to the rays of light and having recorded thereon lines with a non-magnetic material opaque to said rays of light.

4. As a new article of manufacture, a phonographic record comprising the lines of record and the sheet or plate on which said lines are made; the sheet or plate of a material transparent to the rays of light and the lines of record of a non-magnetic material opaque to the rays of light;

5. As a new article of manufacture, a record comprising a flexible transparent sheet having recorded thereon'with opaque nonmagnetic material phonographic characters.

6. As a new article of manufacture, a tracing cloth having recorded thereon opaque laterally undulating phonographic lines of record.

1 In testimony'whereof I affix my signature .in presence of two witnesses.
